BY I M United tates Patent 2,999,377 PADLOCK HOUSING Royce L. Raye, 1652Perryton Drive, Dallas, Tex. Filed May 11, 1960, Ser. No. 28,477 2Claims. (Cl. 70-32) This invention relates to a padlock housing, and hasas its primary object the provision of an improved padlock wherein thetumblers, cam and other working parts of the lock are positioned in acompact, self-enclosed housing so connected and held together that theshackle and bolt cannot be forced open with a screwdriver or othersimilar tool by thieves.

An additional object of the invention is the provision of such a lockwherein the component parts fit tightly and snugly together leavingsubstantially a hair line which precludes the introduction of any toolinto the working parts.

Still another object of the invention is the provision of such a lockwhich is exceptionally sturdy and durable in construction, reliable andefiicient in operation and relatively simple and inexpensive tomanufacture and assemble.

Other objects will in part be obvious and in part be pointed out as thedescription of the invention proceeds and shown in the accompanyingdrawing where there is disclosed a preferred embodiment of thisinventive concept.

In the drawing:

FIGURE 1 is a perspective view of one form of lock embodying features ofthe instant invention, the key therefor being indicated in dotted lines.

FIGURE 2 is a side elevational view of the component parts of the lockin separated position, certain concealed parts being shown in dottedlines.

FIGURE 3 is an elevational view of the inside of one portion of thelock.

FIGURE 4 is an inside view in elevation of the on posite portion of thelock.

Similar reference characters refer to similar parts throughout theseveral views of the drawing.

Having reference now to the drawings in detail, there is generallyindicated at a lock constructed in accordance with the instantinvention, which comprises a male half or portion 11 and a correspondingfemale portion 12. The portions 11 and 12 are relatively solid heavyduty material, and instead of the conventional shackle which may bereadily pried apart or broken, the body of the lock itself is providedwith an indentation, formed of two cutaway portions 13 and 14 on theinner faces of the relative components 11 and 12, as best shown in FIG.2.

The male member 11 has positioned therein a conventional lock barrel,generally indicated at 15, which contains the usual tumblers (notshown), and which termimates in the threaded male members 16. Member 16is adapted to be received in a threaded socket 17, and the lockmechanism is operated by a conventional key 18. A pin 19 carried by themember 12 engages in the corresponding socket 29 carried by the memberH, to prevent rotation of the parts when the key turns to turn the lockbarrel 15. In order to insure tight fitting of the parts, and further topreclude rotation, the member 11 is provided with afianged shoulder 21,surrounding the barrel portion 16, and integral with the face of theinner side of member '11, which member 21 is adapted to seat in acorresponding groove or socket 22 in the opposed member 12. Bothshoulder 21 and socket 22 are provided with flat portions 23 and 24,respectively, to further resist rotation of the components. When thelock is in the assembled position as shown in FIG. 1, it will be seenthat the co-acting cutaway portions 13 and 14 form a relatively snugsocket which is adapted to be fitted about any desired article to belocked, the fit being very snug, so that a screwdriver or pry bar willnot be permitted entry to pry the components apart. Ad-

ditionally, it will be seen that due to the previously describedarrangement of parts, the two members 11 and 12 fit together snugly insubstantially a hairline 25, as seen in FIG. 1, so that it is impossibleto insert any sort of prying instrument at the end of the interior ofthe lock to gain access to the lock barrel or tumblers.

From the foregoing it will now be seen that there is herein provided animproved padlock housing, which accomplishes all the objects of thisinvention, and others, including many advantages of great practicalutility and commercial importance.

As many embodiments may be made of this inventive concept, and as manymodifications may be made in the embodiment hereinbefore shown anddescribed, it is to be understood that all matter herein is to beinterpreted merely as illustrative and not in a limiting sense.

I claim:

1. A padlock housing comprising in combination a male member including arelatively heavy housing having an inner face, a generally circularshoulder flange formed on said face and having a flat face on a portionof its circumference, a lock barrel in said housing, a threadedextension on said barrel extending from said inner face and through saidshoulder flange, the inner face of said male housing member having aninwardly extending bore adjacent said extension, a female membercomprising a second relatively heavy housing including a confrontinginner face, a threaded socket therein for reception of said threadedextension, a generally circular countersink surrounding said threadedsocket, said countersink having wall portions complementary to the wallportions of the shoulder flange on said male member and adapted toreceive the same, a pin extending outwardly from the confronting innerface of said female member and extending into the bore in said malemember, said shoulder flange and counter-sink and said pin and borepreventing relative rotation of said male and female members when inlocked position, and a recess extending into at least one of saidhousings from the inner face thereof for the reception of an article tobe locked.

2. A structure as defined in claim 1 wherein said male andfemale membersinclude wall portions defining identical recesses, said recesses beingcomplementary when said male and female members are in a locked positionwhereby an article to be locked is held therein.
